My invention relates to locomotive trucks way l of each roller-bearing is mounted on' of the two-wheel type, in which the bearings the axle and is held between the' shoulder -16 for the axles of the truck are on the inner on the axle and a sleeve 17, whichextends sideof the wheels.

The axle extends entirely through the housing and is mounted on roller-bearings in the casings at the end o1" the housing, while the springs are carried by links which are allowed to swing on integral brackets projeeting vfrom each end Vof the housing. These brackets are at theupper part of the v m housing, consequently, the links can be long.

a radius bar havingztwo members, one'member extending from one endrof the housing and the other extending from the other end 2;, of the housing, both members of the bar uniting at a pivot bearing; an integral kbrace extending 'rorn each member 'of the radius bar to the underside of the casings of the housing; and laterally extending brackets projecting from each side of the housing and also formed integralwith said housing.

2. The combination in a two-wheel swingtruck, of an integral casting consisting of a cylindrical transverse housing, arranged to .,.f entirely enclose the axle, said housing beingv enlarged at each end toY form a casing for roller-bearings; an integral radiusl bar extending rom the casing' integral brackets n 7 formed on the casingabild projecting from 40 each side thereof;links suspended from said brackets; springs carried by the links,`0ne spring being on one side of the housing and the other springbeing on the opposite side thereof; a longitudinal bolster secured to 4i the springs; and a center pin projecting from the bolster.
